After rising to fame with adventure/ chase novels in The Firm and The Pelican Brief, John Grisham has been experimenting with different narrative forms within the legal fiction subgenre. He is a legal expert, and his novels go into great detail on aspects of the legal profession such as ambulance chasing, jury deliberation, and inheritance law in The Rainmaker, The Runaway Jury, and The Testament, respectively. In The Chamber, Grisham focuses on the death penalty and its execution. With The Brethren, Grisham continues to focus on the legal system by having his main antagonists be ex-judges in prison, partnered with a crooked lawyer. However, Grisham continues to attempt to develop his range in this novel, not only staying far from any real courtroom action but including a full-fledged spy plot for the first time.
